SPECIFICATION forming part of LettersPatent No. 402,617, dated May 7, 1889.

Application led September 8, 1888. Serial No. 284,904. (No model.)

To all whom, it may concern:

Be it known that I, ISRAEL M. ROSE, a citizen. of .the United States, and a resident of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Lighting Devices, of which the ,following is a full, clear, and exact description, reference being had io the drawings which accompany and form part of this specification.

. This invention is an improvement upon the device set out in Letters Patent No. 196,706, granted to me October 30, 1877, and, while involving the same general principles of invention,`broadly considered, it differs specifically therefrom in many Ways.

The obj ect lof my invention is to provide a suitable portable lamp or illuminating device which is compact and contains the medium for ignition.

In carrying out my invention I employ a case in which the lamp-cylinder proper is containedV and free to rotate. This lamp-cylinder is provided with a worm or screw-thread formed upon its circumference and .adapted to raise or push up a tape or strip having pellets of combustible material, which is ignited by the frictional contact of a striker carried by the cylinder and brought into action by the rotation of said cylinder. It will thus be seen that the act of rotating the lamp-cylinder performs the du al function of feeding the igniting tape or strip and also moving the striker in contact with the pellet to ignite it.

The details preferred are shown in the drawings; but they may be varied without departing from the spirit of my invention.

In the drawings, Figure lis a sectional ele'- vation of a portable lamp embodying my invention on line @c oc of Fig. 2. Fig. 2 is a sectional plan view in line y y, Fig. l. Fig. 8 is a sectional plan view of lines fcc, Fig. l. Fig. 4t is a perspective view of the tension-spring which holds the lamp-cylinder from rotating and presses upon and guides the tape or strip. Fig. 5 is a side elevation of the igniting tape -or strip. Figs. 6 and 7 are elevations, with part in section, of my improved lamp attached to a candle-stand for convenient handling in with a worm or screw, O, and also a preferablyflexible striker-point, J. This cylinderA fits loosely into a case, D, having the enlarged upper end, cl, to receive the worm or screw and furnish a shoulder to prevent they downward movement of the cylinder. The plug E, at the bottom, has a iiange, e, which its over the lower edge of the case D and prevents upward movement of the cylinder in the case. The case D, it will thus be seen, acts as a covering and also as a journal-box for the cylinder and worm, and may also form a receptacle for the igniting-strip. The combustible material used in the lamp is preferably conducted by a wick coiled up in the cylinder and saturated with any hydrocarbon or other burning- Iiuid. It is evident that, so far as my invention is concerned, the combustible may be a wax taper or a candle, or any other suitable Haine-giving substance or structure.

The upper end of the case D is provided with a tightly-fittin g cap, F, preferably hinged,

as shown. The case D, at one side,is bent to form a longitudinal groove, G, for holding the igniting tape or stripI. this groove is left open, and a spring-tongue, H, secured to the case at g to forni a continuation of the said tape-guide. This tongue has two side arms, 7i., which press inwardly upon the cylinder A and prevent any tendency to free rotation, and also hold the tape or strip up, so that there may be an elastic or flexible contact between the striker and the tape or strip. f

The tape or strip I is shown in Fig, 5, and consists of a narrow strip of heavy paper hav ing a series of pellets or projections of combustible or explosive ignitingmaterial, t', forming a sort of rack. This tape or strip is pushed up through the bottom of the groove G, the edge e of the plugflange being cut away to admit the tape or strip, and the screw or worm The upper part of .Y

C works in connection with the projections or pellets 2', and with one revolution raises or pushes the tape or strip up one pellet or proj ection, and simultaneously causes the striker J to scratch over or into the igniting or explosive material, causing it to flame or flash out laterally and ignite the wick of the lamp.

It will be observed that the feeding screw or worm is used to elevate the igniting tape or strip and pellets or projections in proper position to be acted upon and ignited by the striker, and also perform the important purpose of separating the pellets or projections nearest the one being consumed, by reason of the screw-thread passing upon the paper strip between the pellets engaged as shown, Fig. 1, thus preventing the consuming pellet from communicating with and destroying` the pellet or pellets nearest to it. It is evident that the construction for accomplishing these results here shown is excellent and cheap, and is the preferred form in practice; but it is apparent that the details may be modified somewhat and still accomplish the same result, but not necessarily departing from the invention.

In Fig. 6 I have shown my improved portable lamp supported in a holder like a candlestick. In this case the flanges e of the plug E are pressed under the projections 7s in the holder K, and so made to stand upright.

In Fig. 7 I have shown another modification of my improvementapplied to a candle-stand, and in this case the plug E is dispensed with and the lamp-cylinder is made to screw direct-ly into the candle-stand, which is made hollow at S to hold the burning-fluid, and the lamp-cylinder may be rotated by turning the candle stand or holder K.

In the case shown in Fig. 8 I have applied my feeding and i gniting device to a gas-burner. The hollow wick-cylinder is dispensed with in this case, and the feeding-screw for the igniting-tape strip may be made solid. The feeding device and tape-strip holder is supported close to the side of the burner by a clamp, T. In this case the gas is first turned on, and then the feeding and igniting screw is lnoved to produce the flash or Haine to light the gas.

Having now described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a case, an ignitingtape strip guided therein, said tape strip having pellets or projections of combustible material or explosive material capable of being ignited by friction, a lamp-vessel, also held in the case, said lamp-vessel being provided with an oil and wick reservoir, the wick projecting from the top of said reservoir in close proximity to the igniting-tape, a feed-worm for feeding the tape strip through the case, the thread of said feed-worm separating the upper pellets from each other, and a striker to press or scratch upon the combustible or explosive material on the tape strip to ignite or explode it.

2. The combination of a case, a tape 'strip having pellets or projections of combustible or explosive material capable of being ignited by friction, a lamp-cylinder being provided with an oil and wick reservoir, the wick projecting from the top of said reservoir in close proximity to the igniting-tape, and said lampcylinder having a worm to work in connection with said pellets on the tape strip to feed them through the case.
